But eagles are currently showing signs of mating season in their eagle ways, some by starting to prepare nests and others by leaving the area.

Raging hormones signal the end of eagle viewing season along the Delaware River.

"We give them their privacy," said Ruth Randone with the Delaware Highlands Conservancy and Eagle Institute.

"This is eagle paradise," Randone said.

Eagles need clean, open water for fish. In Canada and northern New York, when the water freezes, eagles head south to the Delaware River.

In Lackawaxen, there are two pairs of eagles and three immature eagles that are year-round residents.

Now those visiting birds are starting to leave for their northern homes, so this may be the last weekend for eagle viewing.

Randone is in an Eagle Institute winter field office, a little blue house just a few steps from the Pennsylvania side of the Roebling Bridge in Lackawaxen.

"It's like a chamber of commerce for people who want to see eagles in the wild," Randone said.

There is coffee, hot chocolate, a short film, and a large eagle nest — an excellent photo opportunity. Plus, Randone or other volunteers will tell you everything you want to know about eagles.

Just down the street, in front of the Zane Grey house, is a river boat launch where throughout the winter, eagle enthusiasts gather to watch bald eagles, perched on trees, scanning over the river and gliding in to pluck a fish from the water.

Sometimes there is drama when an eagle snatches a fish from an otter's slippery mitts.

That is why Ben Franklin called the eagle a thieving, opportunistic bird and preferred the polite turkey as the national emblem, Randone said.

It is surprising how many people gather at the viewing area in sleepy Lackawaxen.

Many have binoculars, sighting scopes or cameras with telephoto lenses longer than an arm.

Eagle paparazzi.

Volunteers in orange vests will lend a scope or binoculars for a close up view of eagles in the trees from 9 a.m. to 4 p.m. on Saturdays and Sundays, although it is just as thrilling to watch them fly with a naked eye.

Right now there are dozens of eagles visiting. If you have a chance this weekend, go see one of the most majestic sites available in Pike County.
